and then five minutes later the supervisor came over and said to me and this other lad that one of the girls said they heard a wolfwhistle in this area and that he doesn't know who it was but it's cause for instant dismissal

and one of them called my manager 'sweetheart' (as an insult), everyone else glossed over it but I was raging. Its such a weird thing to do in work, less acceptable than throwing a punch or stealing someones lunch.
